Lindsay Lohan is reportedly dating Liam Neeson's son.

The 27-year-old actress - who was most recently linked with 19-year-old model Liam Dean - was seen growing close to Michael, 18, at a party last week ago, and again at Finale nightspot in New York City and onlookers claim they even spent time in the women's bathroom away from other revellers. "Lindsay seems to have this thing for younger men at the moment. They were together at a house party of one of Lindsay's stylist friends before Thanksgiving, and were together at Finale on Friday. Lindsay was seen leading him into the women's bathroom, hand-in-hand," a source said.

Despite her closeness to Michael at the nightspot, Lindsay - who was also linked to teenage Ralph Lauren model Morgan O'Connor earlier this year - also spent time there with Dean. "The odd thing was that Dean was with them all night, even though Lindsay had been seeing him, too," the source added to the New York Post's Page Six column.

However, a spokesperson for Liam insisted "it's not true" that Michael - whose mother is the actor's late wife Natasha Redgrave - is dating Lindsay, and the troubled actress' representative added, "Lindsay is friends with Michael but they are not dating."
